The photograph above shows some rocks in Great Smoky Mountains National Park.
From looking at the rocks, and what you know about the park, a likely story is that:
A) These rocks were buried deeply and squeezed in a continent-continent collision, and then
brought to the surface as overlying rocks were eroded.
B) These rocks are really marmot #2.
C) These rocks were sheared in the great slide-past fault that slid rocks from Florida up to the
North-Carolina/Tennessee border to form the Smokies.
D) These rocks were buried deeply and squeezed in a continent-continent collision, and then
brought to the surface in one of the giant volcanic eruptions that built the Smokies.
E) These rocks were stretched and then snapped back, bending as they did so and making an
earthquake.
Feedback: The squeezing and heating of an obduction zone have changed these rocks from mud
to the folded schist seen here, and then erosion has revealed the rocks at the surface. There were
large volcanoes near where the Smokies are before the Smokies formed, but those volcanoes
ended when subduction ceased and obduction started to build the Smokies. Some slide-past
motion did occur in the Appalachians, but not a huge amount, and the Smokies were not brought
up from Florida.
